我无法滚动一个片段的recyclerView

Question

我在滑动标签布局中有6个片段。他们都在其中实施了RecyclerView。我已经填充了RecyclerView。但我其中一个片段不允许我滚动，但其余的工作正常。

见下面的GIF：

This is my problem

Genres.java

public class Genres extends Fragment { 


private static final String TAG = "Genres"; 
RecyclerView recyclerView_genre; 
GenresAdapter genresAdapter; 
ArrayList<GenresModel> Genrelist = new ArrayList<>(); 
long genreId; 
String genreName; 
Cursor genrecursor; 

@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
    View view = inflater.inflate(R.layout.genres_activity, container, false); 

    recyclerView_genre = view.findViewById(R.id.recyclerView_genre); 
    recyclerView_genre.setHasFixedSize(true); 
    LinearLayoutManager genreLayout = new LinearLayoutManager(getContext()); 
    recyclerView_genre.setLayoutManager(genreLayout); 




    String[] proj1 = {MediaStore.Audio.Genres.NAME, MediaStore.Audio.Genres._ID}; 


    genrecursor=getActivity().getContentResolver().query(MediaStore.Audio.Genres.EXTERNAL_CONTENT_URI,proj1,null, null, null); 

    if (genrecursor != null) { 
     if (genrecursor.moveToFirst()) { 
      do { 

       genreId = genrecursor.getLong(genrecursor.getColumnIndexOrThrow(MediaStore.Audio.Genres._ID)); 
       genreName = genrecursor.getString(genrecursor.getColumnIndexOrThrow(MediaStore.Audio.Genres.NAME)); 

       GenresModel genresModel = new GenresModel(genreId,genreName); 
       Genrelist.add(genresModel); 



       Collections.sort(Genrelist, new Comparator<GenresModel>() { 
        @Override 
        public int compare(GenresModel lhs, GenresModel rhs) { 
         return lhs.getGenreName().compareTo(rhs.getGenreName()); 
        } 
       }); 

      } while (genrecursor.moveToNext()); 
     } 

    } 
    genrecursor.close(); 





    genresAdapter = new GenresAdapter(getContext(),Genrelist); 
    recyclerView_genre.setAdapter(genresAdapter); 
    genresAdapter.notifyDataSetChanged(); 

    return view; 
} 

GenresAdapter.java

public class GenresAdapter extends RecyclerView.Adapter<GenresAdapter.GenresHolder> { 

Context gContext; 
ArrayList<GenresModel> GenreList = new ArrayList<>(); 

public GenresAdapter(Context gContext, ArrayList<GenresModel> genreList) { 
    this.gContext = gContext; 
    GenreList = genreList; 
} 

@Override 
public GenresAdapter.GenresHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View view3 = LayoutInflater.from(gContext).inflate(R.layout.row_genre, parent, false); 
    return new GenresHolder(view3); 
} 

@Override 
public void onBindViewHolder(GenresAdapter.GenresHolder holder, int position) { 

    final GenresModel genresModel1 = GenreList.get(position); 

    holder.genreText.setText(genresModel1.getGenreName()); 

} 

@Override 
public int getItemCount() { 
    return GenreList.size(); 
} 

public class GenresHolder extends RecyclerView.ViewHolder { 

    TextView genreText; 

    public GenresHolder(View itemView) { 
     super(itemView); 

     genreText = itemView.findViewById(R.id.genreText); 
    } 
} 
} 

activity_genre.xml

<?xml version="1.0" encoding="utf-8"?>

</LinearLayout> 

Answer 1

我发现了自己的解决方案。其实问题出在视图转换上。我将https://github.com/geftimov/android-viewpager-transformers/wiki/CubeOutTransformer应用于我的观看者，由于某种原因，我的第一个3片段正在工作，而其余的则不是！
